I think it’s going to rain today (when it’s wet, it’s very very wet)

I took Rosie the truffle machine for a walk around the farm just before dark yesterday. We were both a bit stir-crazy after four days of cold, cold rain and a couple of days of screaming southerlies that brought snow to our hills. The ground passed field capacity at the beginning of last week, when an atmospheric river brought torrential downpours and flooding to much of the South Island. Now the soil is sodden, quivering with water and oozing mud at every footstep. Every drop of extra rain is taking that mud and sluicing it down to the river. A stream runs through my black truffle plantation. I spent this afternoon digging a drainage trench. Truffles don’t enjoy sitting in water. My crop might rot. The Waipara is roaring along at the bottom of our cliff at about 50 cumecs ((Cubic metres per second.)), an impressive sight for a river that normally dribbles down to the sea at under a cumec. It peaked last week at about 110 cumecs. The riverbed will have been reshaped. But we got off lightly.

Over the last couple of days the New Zealand news has been dominated by extreme weather. The southerly storm that soaked us also battered Wellington and brought deep snow ((The Mt Hutt ski field got 2.8 meters of snow — just over 9 feet in the old money — a record start to the season. Take a look at the green line on their snow graph to get some sense of the context.)) to much of the South Island. It made for compelling pictures. But what’s going on elsewhere in the world is even more dramatic:

Is it really six months since I posted the last open thread? I do apologise — please avail yourselves of the facility. I’m busy battening down the hatches before the first big winter storm hits, and preparing for the first Climate Show recording in a long while. Meanwhile, severe weather in Europe is striking very close to my heart, with a dramatic hailstorm devastating vineyards around Vouvray ((NZ can grow excellent Chenin Blanc — the grape of Vouvray — and make a wine that more than stands comparison with its French antecedents. I tasted the 2001 Forrest Chenin Blanc a few weeks ago, and it was quite magnificent.)) in the Loire Valley. And in Britain, the Met Office has called a meeting to see if they can tease out why they’ve had the recent run of wet summers and sharp cold spells in winter. The influence of the Arctic is definitely up for discussion…

McKibben: NZ needs to move away from oil and coal

Bill McKibben‘s on the New Zealand leg of his Do The Maths downunder tour, and I got the chance for a quick chat with him earlier today ((Rosie the truffle machine would like to apologise for her decision to whimper in the background.)). Bill lays out the essence of the carbon budget we have to live within if we’re to avoid roaring past 2ºC, explains the carbon finance bubble, discusses China’s approach to renewables, and why NZ should avoid exploiting its oil and coal reserves. See Bill in Dunedin tonight, and Wellington tomorrow.

TDB today: Europe floods as Arctic melts

In my column at The Daily Blog today, I ruminate on the links between the historic and damaging floods in central Europe and the rapid warming of the Arctic. What will it take to make the world’s leaders wake up to the rapid changes that are happening now? Comments at TDB, please…

NZCCC 2013: Jim Renwick on Antarctic sea ice, SAM and ozone

Here’s the final interview I recorded at last week’s NZ Climate Change Conference in Palmerston North: VUW’s Dr Jim Renwick ((Apologies to Jim for inadvertently using the British pronunciation of his surname in the introduction. I’m told that my usage is a reliable indicator of a migrant from the UK… )) talking about the complex relationship between the southern annular mode — a north-south movement of the westerly winds that blow around Antarctica — sea ice growth and the ozone hole. It’s interesting stuff, not least because SAM has a significant impact on NZ weather and climate, and how it might change in the future is a very big factor in projecting southern hemisphere climates in a warmer world. The abstract of his conference presentation, Antarctic sea ice, the SAM, and the future of the ozone hole, is here.
